Please always tell us what operating system you're using when you start a thread like this.

Some systems have a utility named dircmp that, among other things, can tell you what files are missing from either of two directories given as operands and, for files that are present in both directories, tell you whether or not the contents of those pairs of files have the same contents.

ckdist

CKDIST(1)						    BSD General Commands Manual 						 CKDIST(1)

NAME

     ckdist -- check software distributions

SYNOPSIS

     ckdist [-airsx] [-d dir] [-n name] [-t type] file ...

DESCRIPTION

     The ckdist utility reads ``checksum'' files (which are assumed to specify components of a software distribution) and verifies the integrity
     of the distribution by validating the checksum of each component file.  Both MD5 (128-bit ``message digest'') and .inf (32-bit CRC) checksum
     formats are supported.

     The file operands may refer to regular files or to directories.  Regular files named md5, or which have an .md5 or an .inf extension, are
     assumed to be of the implied type, otherwise format is determined from content.  If a directory is specified, it is searched for appropri-
     ately-named files only.

     The options are as follows:

	   -a	     Report on all distribution components, not just those in respect of which errors are detected.

	   -i	     Ignore missing distribution components.

	   -r	     Search specified directories recursively.

	   -s	     Suppress complaints about inaccessible checksum files and directories.

	   -x	     Verify the existence of distribution components (and also check sizes, in the case of .inf files), but omit the more time-
		     consuming step of actually computing and comparing checksums.

	   -d dir    Look for distribution components in the directory dir.

	   -n name   Access distribution components using the filename name.  When accessing .inf file components, append the appropriate exten-
		     sion to the filename.

	   -t type   Assume that all specified checksum files are of the format type, and search directories only for files in this format (where
		     type is either md5 or inf).

EXIT STATUS

     The ckdist utility exits with one of the following values:

     0	     No errors were detected.

     1	     Errors were found in a distribution.

     2	     Usage errors, inaccessible input files, or other system errors were encountered.

SEE ALSO

     cksum(1), md5(1)

NOTES

     Both BSD and DOS versions of ckdist are available.
